Fourth-seeded North Dakota upset top-seeded Wisconsin in the Midwest Regional Semifinals, 5-2. The Badgers tied the game at 2 with half a period to go, but O’Donnell’s slapshot from the right point hit teammate Mark MacMillan in the back and bounced into the net to give UND a lead they’d never relinquish. Panthers prospect Rocco Grimaldi scored two empty net goals to give him three goals in the game and seal the win for the former Sioux. UND will meet Ferris State on Saturday for the right to go to the Frozen Four.

Friars goalie Jon Gillies stopped all 37 shots he faced to shut out the second-seeded Bobcats and lead third-seeded Providence to within one win of the Frozen Four. Providence will play Union on Saturday. Peca’s junior season is over and it’s possible he gets a contract offer from Tampa Bay to leave school and join AHL Syracuse. He told the Tampa Tribune’s Erik Erlendsson in July that he’d be open to leaving school after his junior season. Whether Lightning GM Steve Yzerman thinks pro hockey is the best thing for Peca now and next year is another story. There isn’t a lot of room in the Syracuse forward ranks for next season. Peca is a special talent with impressive intangibles. He played center this year for the first time in college. He could return to the Bobcats as their frontline center.
